Assistive technology and risks of IVF
IVF refers to the process of fertilizing and cultivating the germ cells of both men and women in vitro to form an embryo through assisted reproductive technology, and then transferring the embryo to the woman's uterus to achieve pregnancy. Bengbu is a city in Anhui Province, China. Many hospitals provide IVF assisted technology. The development of IVF technology has brought hope to many infertile patients, but there are also some risks.
Auxiliary technology I: In vitro fertilization
In vitro fertilization is one of the key steps in IVF technology. It combines female eggs and male sperm in an in vitro culture dish to fertilize and develop them into embryos. In the hospitals of Bengbu City, the common in vitro fertilization techniques include apical development and intracytoplasmic sperm injection. The acrosomal development is to put sperm and egg together, and then the sperm enters the egg through the acrosome to fertilize. Intracytoplasmic sperm injection is to insert a tiny glass injection needle into the egg, inject a single sperm, and wait for fertilization to occur. With correct operation, these technologies can significantly improve the probability of IVF successful pregnancy.
However, in vitro fertilization also has certain risks. First, the process of egg retrieval may cause ovarian hyperstimulation syndrome, leading to ovarian swelling, abdominal pain and other discomfort. Secondly, in the process of in vitro fertilization, sometimes sperm and egg are not easy to combine smoothly, leading to fertilization failure. Third, the implantation rate of embryos transferred after in vitro fertilization is also limited, and there is the possibility of embryo implantation failure. Therefore, patients should fully understand these risks and fully communicate with doctors when choosing IVF technology.
Auxiliary technology II: embryo transfer
Embryo transfer is another important step in IVF technology. After in vitro fertilization, pregnancy is achieved by transferring the embryo into the woman's uterus. Bengbu hospitals use a variety of embryo transfer methods, including traditional intrauterine transplantation and hysteroscopic assisted transplantation. These technologies can not only increase the success rate of IVF, but also reduce the damage to the woman's body.
However, embryo transfer also comes with some risks. First of all, embryo transfer is not necessarily successful, the implantation rate is limited, and multiple transfers may be required to successfully conceive. Secondly, early pregnancy complications may occur after embryo transfer, such as embryo implantation failure, early abortion, etc. In addition, the endometrium may be damaged during the transplantation process, leading to complications such as fallopian tube blockage. Therefore, patients should fully understand these risks and make joint decisions with doctors before embryo transfer.
Auxiliary technology III: embryo screening
Embryo screening is an optional step in IVF technology. Normal embryos can be selected for transplantation through gene testing and chromosome screening of embryos. Bengbu hospitals also provide embryo screening technologies, such as gene chip, PGS and PGD. Embryo screening can eliminate some risks of genetic diseases and improve the quality and success rate of transferred embryos.
However, embryo screening also has some risks. First of all, embryo screening technology is not completely accurate, and there is a certain error rate. Secondly, genetic testing and chromosome screening of embryos need special equipment and technology, and the cost is high. In addition, the screening process may cause some damage to the embryo, resulting in abnormal embryonic development or inability to transfer. Therefore, when selecting embryo screening technology, patients need to consider the risks and benefits comprehensively.
Overview of auxiliary technologies and risks
The auxiliary technologies of IVF include in vitro fertilization, embryo transfer and embryo screening. While these technologies increase the success rate of IVF, they also have certain risks. IVF may cause ovarian hyperstimulation syndrome, fertilization failure and embryo implantation failure; Embryo transfer may lead to low implantation rate and early complications; Embryo screening may have risks such as accuracy problems, high costs and possible damage to embryos. Therefore, when choosing IVF assisted technology, patients need to fully understand these risks, and fully communicate and make decisions with doctors.
